### Function

# GLib get_user_data_dir

since: 2.6

#### Declaration [src]

    const gchar*
    g_get_user_data_dir (
      void
    )

#### Description [src]

Returns a base directory in which to access application data such as icons that is customized for a particular user.

On UNIX platforms this is determined using the mechanisms described in the XDG Base Directory Specification. In this case the directory retrieved will be `XDG_DATA_HOME`.

On Windows it follows XDG Base Directory Specification if `XDG_DATA_HOME` is defined. If `XDG_DATA_HOME` is undefined, the folder to use for local (as opposed to roaming) application data is used instead. See the documentation for `FOLDERID_LocalAppData`. Note that in this case on Windows it will be the same as what `g_get_user_config_dir()` returns.

The return value is cached and modifying it at runtime is not supported, as it’s not thread-safe to modify environment variables at runtime.

Available since: 2.6

#### Return value

Type: `const gchar*`

A string owned by GLib that must not be modified or freed.

The data is owned by the called function.
The value is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows.
